    Hello Kai,

    I am not aware of any devices that can work down to 3V that I am responsible for. The TPS92690 or TPS92691 in a buck-boost configuration could do it but only if there is another supply >4.5V to power the VIN pin with. However I will notify another group about this in case they have anything more suited for these specs.

    Regards,

    Clint

    Hello Kai,

    I got some suggestions and it looks like the TPS61500 may work for you in SEPIC configuration. There is a similar device called the TPS61175 that is similar and has a SEPIC app note if that helps. I'm not very familiar with either so if you need any help let me know and I can get the right people in contact with you.

    Regards,

    Clint
